What does x - 3y = -15 equal

y=1/3x+5

Step-by-step explanation:

I believe this question is turn in to slope-intercept form. If it's not, please let me know. So slope-intercept form is y=mx+b and on the question, they use standard form. Standard form is Ax+Bx=C. To turn standard form into slope-intercept form, you simply make you're y value alone on one side. So you're going to move x to other side my subtracting x on both sides. -3y=-x-15. Right now, we are almost done. We just have to make y own their self which means that y must me one. To make it as one, you will divide -3 on both sides. y=1/3x+5. Make sure in this step, you have to look very careful with negative numbers. If you multiply or divide negative number to negative number, it turns in the positive. So x-3y=-15 is equal to y=1/3x+5.

a. is correct
